Rare Spiders in Florida

Brown Recluse

• The brown recluse spider, while common in many parts of the country, is quite rare in Florida -- fortunately so, because its venomous bite can cause a serious wound. The dark brown spiders grow to about 3/8-inch long and tend to hide in dark places such as under rocks or in woodpiles. They can sometimes be found in homes, usually in dark closet corners or in abandoned boxes in basements or attics. The brown recluse is not native to Florida, and is so rare that people often mistake it for other species, such as the wolf spider.

Chilean Recluse

• The Chilean recluse, like the brown recluse, is not native to Florida. It grows to about 5/8-inch long and is pale yellow with some reddish brown on its body. The Chilean recluse can be identified by a dark marking on its head that is shaped like a violin. This nocturnal spider likes to hide under rocks and in dark corners like other recluse spiders. Although not aggressive toward people, the Chilean is the largest of the recluse species and has the most toxic bite. Anyone bitten by a Chilean recluse should seek medical attention immediately.

Red Widow

• The red widow, while native to Florida, is considered the most rare widow spider in the country. In Florida this tree-dwelling spider is found only in scrub palmetto habitats. This is a very colorful spider, having red legs and a black body with red spots on the abdomen. The red widow is semi-aggressive and very nervous, so it can pose a threat to humans it encounters. This spider is very poisonous, so it is important to be able to accurately identify it.

Tarantulas

• The tarantula is quite rare in Florida because its natural habitat in the dry, grassy hillsides of Florida have been disturbed by urbanization. Tarantulas live under rocks or in underground burrows. They can grow to 2 1/2 inches long, making them look more intimidating than they actually are. Tarantulas, in fact, are very docile and rarely bite people unless provoked. Their venom is not very potent and usually causes only mild swelling at the location of the bite.

Trapdoor Spider

• Trapdoor spiders became rare in Florida as urbanization destroyed their natural habitat in the state's grassy hills. Although once so numerous they were sold as pets, the trapdoor spider is now an endangered species. They typically live on hillsides, digging 6- to 10-inch burrows that they line with silk. The spider then seals the burrow with a lid, or trap door, giving the spider its name. They grow to about 1 inch long, and females are usually black while males are orange.
